First time accepted submitter minty3 writes "A fibrous dysplasia tumor has been found in the bone of a Neanderthal that is more than 120,000 years old. The world's oldest tumor in a Neanderthal rib was part of a collection of bones, which were excavated more than 100 years ago from a site in Krapina, Croatia. They were X-rayed in the 1980s, and initially didn't reveal the tumor. It was only when scientists took a closer look at a radiograph where a rib fragment appeared to be 'burned out' did they return to the rib and subject it to higher quality scans."
